'6 Claims. (Cl. 4-252) This invention relates to floor bases, sometimes called sanitary bases, on which to mount flush toilets. The plumbing laws or ordinances in many localities require a slab or floor base between the bottom of a flush toilet or water closet and the floor of the room to protect the floor around and beneath the toilet. The health board and plumbing regulations require that the base must be nonabsorbent of water, rigid, durable, have a smooth upper face to facilitate cleaning, fit closely to the floor, with no cracks under it along its periphery, and enable easy mounting and dismounting of the toilet.

An object of this invention is to provide a floor base or platform on which a flush toilet or water closet may be supported, which will meet all requirements of health boards and plumbing regulations of many communities, which can successfully compete as to price and advantages with other acceptable floor bases or platforms, which will be entirely sanitary, which may be easily cleaned, and which will be relatively simple, light in weight, and inexpensive.

Other objects and advantages will appear from the following description of one embodiment of the invention, and the novel features will be particularly pointed out hereinafter in connection with the appended claims.

In the accompanying drawings:

Fig. 1 is a bottom plan view of a base constructed in accordance with this invention;

Fig. 2 is a longitudinal section through the center of the same;

Fig. 3 is a top plan of the same;

Fig. 4 is a sectional elevation through part of a floor, said base, soil pipe and part of a toilet, to illustrate the manner of mounting the toilet, and its connection to the soil pipe; and

Fig. 5 is a fragmentary bottom plan of the parts shown in Fig. 4 as viewed from just below one of the key-hole slots, but on a larger scale.

In the illustrated embodiment of the invention, the base 1 is a generally plate-like, unitary casting or body of rigid material, such as cast metal. Castings of ordinary cast iron or wrought iron are very satisfactory. This base 1 is relatively thin and flat, somewhat rectangular in outline, and has an opening 2 from face to face in its interior face area, preferably somewhat off center of the base, in a direction lengthwise of the base. A tube 3 depends from the under face of the body around the opening 2, and the lower end of the tube has an inturned flange 4 which surrounds and fits the upper end of a soil pipe 19 (Fig. 4).

The upper face of the base is smooth and flat, and is provided with a shallow, endless groove or channel 5 near to, but spaced from the peripheral edge of the base. The peripheral edge of the base is downturned to provide a depending rib or flange 6 on the under face of the base. The body of base 1 is provided with an endless rib or flange 7 depending from its under face, and it surrounds, is spaced from and is concentric with the tube 3. Additional ribs 8 and 9 depend from the under face of the 2,758,316 Patented Aug. 14, 1956 base and connect the peripheral flange or rib 6 with the endless flange or rib 7.

The peripheral flange 6, the endless rib or flange 7 and the ribs 8 and 9 all depend to the same distance so that they will all terminate at their bottom edges in a common plane, and thus will aid in supporting the base 1 uniformly on the floor 10 (Fig. 4) on which the base is to be mounted. The ribs 8 and 9 preferably connect the two corners furthest from the tube 3 to a common point on the endless rib or flange 7, and hence will be in positions somewhat diagonally of the base.

The plate or wall of the base is of uniform thickness except for the tube 3, and the depending ribs or flanges, and is provided with two key-hole, arcuate slots 11 in the portion between the tube 3 and the endless rib or flange 7, but on diametrically opposite sides of the tube 3. These slots 11 run in directions concentrically of the tube. Bolts 12. (Fig. 4) extend upwardly through the slots, with the heads 13 of the bolts beneath the base in the space between the tube 3 and the endless rib or flange 7. The heads 13 are non-circular (see Fig. 5) and are held against rotation by engagement with the exterior of tube 3, or a side of-the endless flange or rib 7, or both, yet the bolt may be slid laterally of itself along the slot 11 through which it passes, to bring the head 13 into alignment with the larger end 14 of that slot through which the head can then pass. This makes it possible to insert a bolt in a slot 11 or remove it therefrom while the base is resting on the floor lltl.

Calking 15 (Fig. 4) is placed in the space between the exterior of said pipe 5 and the interior of tube 3, against the flange 4. The toilet to rests upon the base 1 with its depending discharge tube 17 entering the upper open end of the soil pipe, and with the bolts 12 extending upwardly through apertures in the base of the toilet body, as usual in toilet installations. Sealing calking 18 is disposed upon the upper end of the soil pipe, as shown in Fig. 4.

In use, the base 1 provides a rigid and durable support for the toilet, requiring little or no machining, and its smooth upper face is easy to clean. Any liquid collecting or falling on the base and tending to run off upon the floor will be caught and held in the shallow groove or channel 5 from which it may easily be removed. This prevents soiling of the floor around the toilet. The base is light, yet strong and rigid, and does not objectionably elevate the toilet above the floor level.

It will be understood that various changes in the details, materials and arrangements of parts, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.

We claim:

l. A floor base on which to mount a flush toilet comprising a unitary, relatively flat, somewhat rectangular, cast body of rigid material, having an opening from face to face surrounded by 2. depending tube whose passage terminates approximately at its lower end in an inturned flange, the opening of said passage as defined by said inturned flange being of a size to receive within it and fit closely an end of a soil pipe to which it is to be coupled, said body having a shallow, narrow, moisture collecting groove in its upper face parallel to and spaced from but near its peripheral edge, a downturned peripheral flange, a depending endless rib on its under face concentric with and larger than said tube, and diagonal ribs on its under face, connecting two corners of said peripheral flange with the nearest side of said endless rib, said ribs and said peripheral flange all having the same depth from the upper face of said body, said body having keyhole apertures from face to face in the space between said tube and said endless rib, disposed at diametrically opposite sides of said tube, and running in directions concentrically about said tube, said tube having its axis offset somewhat from the center of said body.
